BOSTON — In 2022, small-scale rooftop solar produced enough energy to power 5. 7 million typical American homes, a tenfold increase over the last decade. That's according to Rooftop Solar on the Rise, a new report unveiled on Tuesday by Environment America Research & Policy. A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity -generating solar panels mounted on the rooftop of a residential or commercial building or structure. Using building-level data, researchers highlight a major untapped opportunity for cleaner, decentralised energy systems. By 2024, this energy source accounted for approximately 11% of the EU's power supply and continues to expand at a rapid pace. To date, most of the capacity installed in the EU. A new EU-wide analysis shows that rooftop solar photovoltaics could supply around 40% of Europe's electricity by 2050.
